MySQLdb is hard to locate

I use this tutorial text as an example, there are others:
#!/usr/bin/python
import MySQLdb
If it produces the following result, then it means MySQLdb module is not installed −
Traceback (most recent call last):
File "test.py", line 3, in <module>
import MySQLdb
ImportError: No module named MySQLdb
To install MySQLdb module, use the following command −
For Ubuntu, use the following command -
$ sudo apt-get install python-pip python-dev libmysqlclient-dev
I have gone trough these steps, more or less as described above.
Problem is that the subdirectory "python" does not exist under /usr/bin/
in my file system. I run Linux Mint 18.3. Python 2.7 seems to be the native version installed in Mint (used for several purposes), but I have also installed Python 3.6.4 and wish to use this for development purposes.
Does anyone know in which directory I could expect to find MySQLdb?
Since #!/usr/bin/python is non existent I wonder - has MySQLdb been properly installed? If it has, I have not after several efforts succeded in locating it.

How to install missing wx module on Python 2.5?

I have developped a tool under python 2.5 and can't upgrade to a newer python version as I need to use an API developped under python 2.5 as well.
I recently tried my tool under another machine and it seems it hasn't wx module installed as you can see below:
>>> import wx
Traceback (most recent call last):
File "<interactive input>", line 1, in <module>
ImportError: No module named wx
So I searched for the wxpython source. However once I tried to install the source with:
D:\tmp\wxPython-4.0.0b2>c:\Python25\python.exe setup.py install
I got following error:
Traceback (most recent call last): File "setup.py", line 15, in
from setuptools import setup, find_packages ImportError: No module named setuptools
I can't either install whl files as I don't have pip.
So, how can I install wxpython for python 2.5 under Windows?
Is there any executable there in the web that I couldn't find? May there be a workaround by copying the wx module from a python directory from another computer?

As I had to install wxpython 2.7.2.0 I finally got it from wxPython2.7-win32-ansi-2.7.2.0-py25.exe.
As stated in Patrick's comment all wxpython executables for any version are under https://sourceforge.net/projects/wxpython/files/wxPython/

Unable to compile python with pyglet in Ubuntu

In Ubuntu 15.10,Running
python3.4 sound.py
leads to this error:
Traceback (most recent call last):
File "sound.py", line 2, in <module>
import pyglet
ImportError: No module named 'pyglet'
I already installed pyglet with running this command:
sudo easy_install -U pyglet
resulting
Searching for pyglet

I am confused about what is missing. I guess there are some confusion about different verions of python, pyglet or Ubuntu.

From the install output it seems that the installed version of pyglet goes to python 2.7 packages. From your command you are explicitly calling python 3.4 There might be a problem there. python 3.4 will not go to 2.7's packages to check for the module.
I suggest that you call the script using python 2.7. running just python is enough (the default env python)
You can take a look at this question on the installation of python 2 and 3 packages too

Django Taggit Module Installation Error: No module named setup tools

The title basically explains it all.
I am running Windows 8 (windows 7 was previously installed... If it helps with answering) and am using Python 2.7.
Upon using the code:
python setup.py install
I am getting this error:
C:\Users\Nicholas\Desktop\taggit>python setup.py install
Traceback (most recent call last):
File "setup.py", line 52, in
from setuptools import setup
ImportError: No module named setuptools
Any help?
Thanks in advance
Nicholas

You need to install setuptools, which allows packages to be configured for your Python installation. It is not included with the default Python installer.
From this link you can download Windows installers for many Python packages (I have linked it directly to setuptools). Make sure you download the version that matches your Python installation.

in Python 3:
pip3 install setuptools
And in Python 2.x:
pip install setuptools

No module named win32console, while running wexpect

I want to run wexpect (the windows port of pexpect) on my Windows 7 64-bit machine. I am getting the following error:
C:\Program Files (x86)\wexpect\build\lib>wexpect.py
Traceback (most recent call last):
File "C:\Program Files (x86)\wexpect\build\lib\wexpect.py", line 97, in <module>
raise ImportError(str(e) + "This package was intended for Windows like operating systems.")
ImportError: No module named win32console This package requires the win32 python packages.This package was intended for Windows like operatin
g systems.
In the code it is failing on the following line:
from win32console import *
I am using Python 2.6.4. I cannot figure out how to install win32console.

Install this: http://sourceforge.net/projects/pywin32/
Edit to add slightly longer explanation: There's a very useful set of Windows-specific Python modules, called PyWin32. I believe win32console is part of that. You can either install PyWin32 on top of the standard python.org release of Python, or you can install ActiveState ActivePython which bundles everything you need all together. I'm using ActivePython and I have a win32console module.

Install wexpect with pip to install all dependencies (inluding pywin32).
pip install wexpect
